My advice for our authors is often some variation of… go outside, listen, breathe deeply and be still; listen to a podcast unrelated to your topic; read for fun (also in an unrelated topic/genre); allow your mind to rest by doing creative just-for-you projects; ask yourself what the block is AND listen (your body knows). And if all else fails and you’ve got a deadline, voice record what you want to write—it alleviates the pressure and self-editing, & helps you fall back in love with your wip.
